Disc Brake Manual Release
It may be required to rotate the winch drum when the hydraulic system is shut down and/or no power is available.
Provisions have been incorporated into the system to accomplish this task. The following procedure must be used:
(1)
Open the ball valve (18) to bypass the piston pump (4A). This will permit freewheeling of the hydraulic motor
(20).
(2)
At the disc brake, remove the hydraulic line from the joystick (5), and connect the line from the hand pump (22)
using the quick-disconnect fittings supplied.
(3)
Activate the hand pump with the lever to draw fluid from the reservoir to apply pressure for manual release of the
disc brake.
(4)
The band brake may be used to control winch drum rotation.
(5)
Release the pressure from the brake line with the screw on the hand pump. This will reapply the disc brake.
(6)
Close the ball valve.
(7)
Connect the brake line from the joystick.
WARNING CAUTION
FOR NORMAL POWERED OPERATION OF THE WINCH, THE BALL VALVE (18) MUST REMAIN
FULLY CLOSED, AND BRAKE LINE MUST REMAIN CONNECTED TO THE JOYSTICK (5). Extreme
caution must be taken to prevent a runaway condition.
